20090283351 | GAS STORAGE SYSTEM, METHOD USING SAME, AND VEHICLE INCORPORATING SAME - Abstract of the Disclosure The invention concerns a gas storage system, in particular for supplying a motor vehicle power source, comprising at least two storage modules (GrA, GrB, GrC) each including an outlet conduit (Ci) connectable, by a quick-connect device (Cri) via an electromagnetic valve (vpA/B/C), to a supply line (L) of a user station, the modules, including for example different capacities, being produced with identical tanks (Ri). The invention is characterized in that the modules are used sequentially allowing one module to be completely emptied before the other module is used, and in that only the first empty module can be replaced with an identical full module, without replacing, at that stage, the other module in operation. | 11-19-2009 |
20090288902 | HOT COMPRESSED GAS VEHICLE - A compressed-air powered drive system for a vehicle (10) or a propeller-driven aircraft (12). In a land vehicle (10), the drive system includes a plurality of air motors (20) each driving a wheel (16) through a transmission device (18). Compressed air from an air storage tank (12) is supplied through a heat exchanger (40) to drive air motors. A fuel is burned in the heat exchanger (40) to provide hot, high pressure air to the first air motors. Water may be injected into the heat exchanger to provide a hot steam. A plurality of air pumps (22) are engaged with and driven by the wheels to pump air into the tank during driving. When braking, the air pumps (22) driven by the wheels (16) recapture kinetic energy by pumping air into the tank. The air motors can also act as pumps to pump air into the tank during braking by reversing the transmission devices. | 11-26-2009 |
20100078253 | PNEUMATIC POWERTRAIN FOR AN AUTOMOTIVE VEHICLE - A pneumatic vehicle is provided with a chassis, wheels, a compressed air tank, a heat exchanger to heat the compressed air, and an air motor driven by the heated air and connected to at least one wheel. A pneumatic vehicle is provided with a chassis, wheels, a compressed air tank, and an air motor driven by the compressed air and connected to a wheel. The vehicle also has a ventilation system for the passenger compartment, a heat exchanger, and a restrictive solenoid valve for directing ventilation system air to the heat exchanger. A pneumatic vehicle is provided with a chassis, wheels, an aluminum compressed air tank, a carbon filament reinforced plastic layer over the tank, a fiberglass and aramid-fiber layer over the carbon filament reinforced plastic layer, and an air motor driven by the compressed air and connected to at least one wheel. | 04-01-2010 |
20100078254 | BODY FOR PNEUMATIC VEHICLE - A pneumatic vehicle is provided with a first and second sub-assembly. The first sub-assembly has a chassis supporting an air tank. The second sub-assembly has part of the vehicle body and is bonded to the first-sub-assembly using a structural adhesive. Another pneumatic vehicle is provided with a first and second sub-assembly. The first sub-assembly has a chassis, air tank, part of the vehicle body, a pair of B-pillars, and a pair of rear rails. The second sub-assembly has a part of the vehicle body, a pair of A-pillars, and a pair of roof rails. A vehicle seat is provided with a seat base and upright seat back providing a seating area. A bladder located in the central region of the seating area inflates to provide two bucket seats, and deflates to provide a bench seat. The vehicle seat also has inflatable inserts to provide cushioning. | 04-01-2010 |
20100096209 | Air-propelled vehicle - An Air-propelled Vehicle complete with wheels mounted on axels, equipped with all appropriate steering, braking, lighting and safety mechanisms required to operate the said Air-propelled Vehicle in a safe manner and that such said Air-propelled Vehicle is propelled in both forward and reverse directions with the propulsion provided by either one or more than one air motors either unidirectional or reversible and such Air-propelled Vehicle also includes, equipment to produce the required compressed air, the storage tanks to store such compressed air, a system of hoses to allow the compressed air to be distributed amongst the various components of the Air-propelled Vehicle and a compressed air flow control mechanism capable of allowing or stopping the compressed air to enter such air motors. | 04-22-2010 |
20120132477 | Compressed Air Engine And Motor Vehicle - A compressed air engine comprises a housing and an impeller body fixed on a primary power output shaft and located within the housing. An ejecting inlet ejects air to the impeller body in the housing. Working chambers are provided on the impeller body. The inner surface of the housing closes the working chambers so that the compressed air ejected to the working chambers pushes the impeller body to rotate and is temporarily stored in the working chamber, and an ejecting outlet is provided on the housing so that the compressed air temporarily stored in the working chamber expands outwards when the compressed air is rotated to the gas ejecting outlet and do work to further push the impeller body to rotate. | 05-31-2012 |

20090000848 | AIR START STEAM ENGINE - A method and system for an external combustion engine operable using at least two different fluids to provide pressure volume work to an engine. The engine is started by providing a compressed fluid at a sufficient pressure to move internal components of the engine that in turn rotate a shaft to generate power. At the same time the compressed fluid is provided to the engine, a liquid fluid is provided to a heater to be heated. The liquid fluid is heated to its boiling point and converted to gas form. Additional heat is provided to increase the pressure of this gas fluid. Once the pressure is increased to a sufficient level, the gas fluid is injected into the engine to generate power. The gas is exhausted from the engine, and is cooled and separated back into the two separate fluids. The initial compressed fluid is recompressed for later use. | 01-01-2009 |
